Energy Savings Opportunities Scheme (ESOS)


What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment initiative for large organisations in the UK. To comply, eligible businesses must complete emissions audits and report at least 90% of their total energy usage to the Environment Agency every four years. ESOS is comprised of four stages with strict deadlines for submission, and failure to comply can result in fines of up to £90k. With the ESOS Phase 3 deadline (December 5th, 2023) quickly approaching, it’s essential that you prepare accordingly to avoid penalisation. 

ESOS is an excellent auditing tool that allows operators to quickly identify ways to optimise efficiency, lower greenhouse gas (GHG) emissions, produce less waste, and significantly reduce gas and electricity bills.

Qualification criteria for ESOS:

  • You have more than 250 employees, OR

  • A turnover of more than £44.1m or an annual balance sheet of at least £37.9m (€43m), OR

  • You are an overseas organisation with over 250 employees in the UK and pay UK income tax.

What are the ESOS deadlines?

  • Phase 2 (passed): December 5th, 2019
  • Phase 3: (Due) December 5th, 2023
  • Phase 4: December 5th, 2027
